Facebook Graph API (Post Interim Plan)

Apart from analysing one of SGAG's popular social network Twitter, we plan to leverage the Facebook Graph API. Drawing from our experience using the twitter API, we are looking to crawl Facebook data in a similar fashion, crawling, retrieving and aggregating post-level Facebook data. Hopefully, this process can yield conclusive results about the SGAG's social network (likes, shares, etc) on Facebook.

Approach (Post Interim Plan)

Step	Expected Result	Notes
1	Collect all post data	Get all posts of SGAG on SGAG page, preferably all posts from 2 years ago to date For each post, look out for 'Like' count, and when Graph API 2.6 is out, look out for the other Facebook reactions as well
2	All user objects for each like, for every post	For each follower, explore whether privacy options by users will limit us to further classify these user objects Analyse 'Like' count per post, and if possible chart 'Likers' social network on a post-level basis Manually categorize posts, like what we did for Twitter, and possibly prune them, to further refine insights
3	"Comment-Level" per post and number of shares on a "user-level"	Analyse posts by its comments Are posts that are highly commented popular? Analyze users who actually "Share" sgag's posts, and their connection with other users

Data Retrieval

Constructing the graph from scratch involved the usage of python code to retrieve posts from SGAG's Facebook account for posts dating back 10 months. This involved connecting to the Facebook graph API programatically to formulate a csv file that resembles this structure:

Post ID	List of Likers	List of Commenters
378167172198277_1187053787976274	10206930900524483;1042647259126948;10204920589409318; ...	10153979571077290;955321504523847;1701864973403904; ...

Where each user ID in List of Likers and List of Commenters are separated by a semicolon, and tagged to each post.

After crawling the Facebook API for ~4.5 Hours, the result is 1600++ posts dating 10 Months ago, with a CSV file size of ~38MB.
